PONERA. Sepala erecta, carnosa, lateralia raajora, basi producta cum 

 pede elongato columnae connata ; dorsale planum. Petala ovalia, basi 

 angustata, libera. Labellum cuneatum, bilobum, ascendens, arcuatum, 

 cum basi columnae articulatum, omnin& nudum. Columna brevis, teres. 

 Anthera membranacea, depressa, 4-locularis. Pollinia 4 , per pana ad- 

 hserentia ; caudiculis binis pulvereis incumbentibus. Stigma subrotun- 



dum, excavatum, subbilabiatum. Herbse terrestres, graminea, sim- 



plices. Folia linearia disticha, vaginis verrucosis. Flores fascictdatt, 

 terminales (?) in cattle folioso, v. axillares in caule defoliate. Ovarium 



breve, conicum, rectum, sessile. , 



Sp. 1. Y.juncifolia (Gen. & Sp. Orch. p. 113.); folns subulatu .canalicu- 

 lars secundis, spica subbiflora terminal! in caule folioso, labello retuso, 



clinandrio mutico . — -Mexico. A single specimen of this rare plant 



exists in Mr. Lambert's herbarium. It has a stem about a span high 

 and extremely narrow leaves which, in the dried state at least, are all 

 directed towards one side. The flowers are separated from each other 

 by an interval of nearly half an inch,

recurvo crenulato, clinandrio mutico.— -Mexico A g^yp^ of 



no beauty, resembling P. striata in the form of its leaves, but different in 



the structure of the flowers. < j ".. . . 



Sp. 3. P. striata; foliis lineari-lanceo atis obhque emarginatis, spica sub- 

 biflora axillari in caule defoliato, labello bilobo integro chnandm den e

Receding in the lip being two-lobed, not acute and recurved, in -its 

 naSfng entire and not crenulated, m the anther-bed having a 

 Si tooth 4ich curves over the anther, and two much smaller blunt 

 teeth on eaclT side of the stigma; it has also the property of flowering 

 on the old leafless stems instead of the young leafy ones. The flowers

 A great many plants of this species are now in thi* 

 countrv having been sent from Guatemala by Mr. Skmner to 

 hSndtand°by Mr. Hartweg to the Horticultural Societv ; 

 but they do not at present seem disposed to flower with the- 

 beauty that is natural to them. I have not seen , more ; than 

 three or four blossoms open ■* a time, nor do 1 ima that a 



much larger number have hitherto made their appearance ;
